3/x + 2/y - 4/xy

Answers

This will reqiure cross multiplication. We multiply by crossing the denominators and numerators. This is the solution : -

3/x + 2/y - 4/xy

= 3y+2x/xy - 4/xy                 (xy is common denominator)

=          3xy + 2x - 4

Which of the following is a function equivalent to f(x) = 3(1.7)4x? A f(x) = 25.06x
B f(x) = 3(8.35)x
C f(x) = 3(8.25x)
D f(x) = 487.97x

Answers

If you would like to find a function which is equivalent to f(x) = 3(1.7)4x, you can do this using the following steps:

f(x) = 3(1.7)4x = 3(1.7)^(4x) = 3(1.7^4)^x = 3(8.35)^x = 3(8.35)x

The correct result would be B f(x) = 3(8.35)x.

Answer:

Option B- $f(x)=3(8.35^x)$
